130 all whom it may concern:

Be itknown that I, Jenn RU'rnv'eN, a citizen of the United States, residing at Detroit, in the county of \Vayne and State of Michigan, lune-invented a new and useful of which the following is a specification. v

The present invention relates to improvements in carburetors, the primary object of the invention being the provision of a car: bureter adapted to be disposed to rest. abo e the exhaust'nnmifold of an explosive engine, the same being supplied with a hydrocarbon fluid, such as gasolene or alcohol, inlet and valve controlled mechanism, whereby the said fluid -is. fed ivithin the.device and amount ofpower therefrom.

through capillary attraction is. so hold that the' airdrawn through the device due'to the action'of the explosive engine will be thoroughlymixed with the hydrocarbon fluid in the proper proportion for the carburete'd air and conveyed directly to the explosive cham- 1 hers of the engine, thus producing adry carbur'eted air,-so as to obtain from the hydrocarbon fluid the highest possible combustion,

thus resulting in a great saving in the consumption of the fluid with the maximum A'further object of the present invention is the provision of a carbureterwhich is composed of a receptacle having upper and lower separated 'ut'communicating chamhers and which has leading thereinto an air. inlet, each chamber being-provided with air filters, so that the moisture in the air is extracted thei'efrom before the commingling of the air with the hydrocarbon fluid to produce the best possible carbureted air before the same is supplied to the explosive engine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangements of parts and inthe details of construction hereinafter described from the spirit of the invention.
